Is everyone a pronoun?

Everyone is an indefinite pronoun meaning “every person.” Indefinite pronouns are nonspecific, and the meaning of “everyone” can vary depending on the context.

For example, it can be used to refer to every person in a particular group (e.g., “everyone at the party had a great time”) or more generally to refer to every person in the world (e.g., “everyone needs to drink water to stay alive”).

People sometimes confuse everyone and every one. However, the indefinite pronoun is always written as one word.
